CQC1 Series High-Duty AC Contactor and Accessories
The CQC1 Series High-Duty AC Contactor and Accessories is a CHAC AC contactor for remote switching and motor control. The page keeps the model-specific technical table and original product images so buyers can verify voltage, current, configuration, mounting and applicable standards before ordering. Final suitability depends on the complete circuit, installation method and destination-market rules.
Product Overview
CQC1 Series High-Duty AC Contactor and Accessories is a AC contactor intended for remote switching and motor control. The current product record identifies it for motor starters, HVAC and automation panels. Use the exact model variant and preserved technical source as the basis for procurement rather than assuming that every family member has the same rating.

Key Features
Typical Applications
Typical use can include motor starters, HVAC and automation panels when the project confirms system voltage, current, fault or surge exposure, conductor and enclosure requirements, and the selected variant’s installation instructions. This page does not replace the project design or the authority having jurisdiction.
Applications and Selection Guide
Use the following decision points with the preserved model data. Product-family descriptions explain intent, but the exact technical table controls the ordered variant.
| Selection point | CQC1 Series High-Duty AC Contactor and Accessories | What the project must confirm |
|---|---|---|
| Application | AC Contactor projects | Confirm the actual system and environment |
| Selection basis | remote switching and motor control | Use the exact model and technical table |
| Installation | Follow the model instructions | Check mounting, clearances and termination |
| Compliance | Use the listed standard where applicable | Verify edition, scope and destination rules |
| Adjacent product | Evaluate the related CHAC family where function differs | Do not substitute without engineering review |

CQC1 Product FAQ
What loads can the CQC1 contactor switch?
Use the published utilization category, operational current and voltage for the selected variant. Resistive, motor and capacitive loads require different checks.
How do I select an AC contactor size?
Start with load current, utilization category, starts per hour, coil voltage, poles and short-circuit coordination. Current alone is not enough.
Can a thermal relay be paired with it?
Where the product record supports the combination, a thermal relay can form a motor starter. Confirm mechanical fit, current range and control wiring.
Which coil voltage should I specify?
Match the control supply shown on the project drawing with the coil option for the exact model. Never assume the coil voltage from the main circuit.
What accessories are available?
Auxiliary contacts, timers, interlocks or other accessories depend on the series and variant. Confirm the compatible accessory list before ordering.
How should a contactor be commissioned?
Verify terminal torque, coil voltage, contact sequence, insulation and operating current, then record the test results.
Confirm the Right CQC1 Configuration
Send the exact model, operating conditions, quantity, destination market and required documents. CHAC will review the request against the published product data.
